Product Introduction

This Air Reservoir 6+9L WG9000360718 is an OEM dual-chamber air storage tank for heavy-duty trucks and commercial vehicles. It features a high-strength steel construction with a 6L+9L split capacity design, corrosion-resistant coating, and precision-threaded ports, engineered to securely store dry compressed air for the vehicle’s pneumatic brake and auxiliary systems under heavy-load operations.

Performance

• Dual-Chamber Design: This 6+9L heavy-duty air reservoir isolates brake circuits and auxiliary systems, ensuring independent air supply and fail-safe operation even if one chamber is compromised—a high performance air storage tank.

• Robust Structural Strength: Constructed from premium high-carbon steel with seamless welding, it withstands extreme pneumatic pressure (up to 1.0MPa) and resists deformation under vehicle vibration or impact.

• Superior Corrosion Resistance: The electrostatic powder-coated finish provides long-lasting protection against road salt, moisture, and debris, preventing rust and extending service life in harsh undercarriage environments.

• OEM Exact Fit: Optimized for Sinotruk heavy-duty truck models, it matches original mounting points and port positions for seamless installation.

Core Function

1. Stores dry, clean compressed air to provide stable pressure for the pneumatic brake system, ensuring responsive braking under heavy loads and long downhill runs—a core part of heavy duty truck brake parts.

2. Separates brake circuits via dual chambers, preventing total brake failure and enhancing vehicle safety.

3. Acts as a buffer to stabilize system pressure, reducing wear on air compressors and valves.

Key Features & Benefits of the WG9000360718 Air Reservoir

This isn’t just another air tank sitting under your chassis—it’s a precision-engineered component that plays a critical role in your vehicle’s safety system. Here’s what makes it stand out:

• Dual-Chamber 6L+9L Split Design: The separated chambers allow independent air storage for primary and secondary brake circuits, adding an extra layer of safety redundancy to your braking system.
• High-Strength Steel Construction: Built from heavy-gauge steel plate, this reservoir withstands continuous high-pressure cycling and road vibration without fatigue cracking.
• Corrosion-Resistant Coating: A factory-applied anti-corrosion surface treatment protects against moisture, road salt, and chemical exposure, significantly extending service life.
• Precision-Threaded Ports: Each inlet and outlet port is machined to exact OEM thread specifications, ensuring leak-free connections with your existing air lines and fittings.
• Direct OEM Replacement: Part number WG9000360718 guarantees a bolt-on fit—no modifications, no adapters, no guesswork during installation.
• Pressure-Tested & Certified: Every unit undergoes rigorous pressure testing before shipment to ensure zero leakage and full compliance with original equipment standards.

In other words, when you install this air reservoir, you’re restoring your truck’s air supply system to its original factory performance. Moreover, the dual-chamber configuration means that even if one circuit experiences a fault, the other continues to supply air to your brakes—a feature that could prevent a catastrophic failure on the road.

Frequently Asked Questions – Air Reservoir WG9000360718

What is the purpose of the dual-chamber (6L+9L) design in this air reservoir?

The dual-chamber design separates the stored compressed air into two independent volumes. This ensures that your truck’s primary and secondary brake circuits each have a dedicated air supply. Consequently, if one chamber or circuit develops a leak, the other chamber continues to provide braking pressure—a critical safety feature for heavy-duty vehicles operating under load.

How do I know if my current air reservoir needs replacement?

Common signs include visible rust or corrosion on the tank body, audible air leaks around the ports or welds, frequent compressor cycling (indicating the system can’t hold pressure), and moisture or oil contamination in the air lines downstream of the reservoir. If your truck’s air pressure gauge drops faster than normal after the engine is shut off, the reservoir is likely compromised.

Is this WG9000360718 air reservoir a genuine OEM part or aftermarket?

This is an OEM-specification replacement part manufactured to the exact dimensional, material, and performance standards of the original SINOTRUK component. It carries the same part number (WG9000360718) and provides a direct bolt-on fit without any modifications required.

What maintenance does the air reservoir require after installation?

Routine maintenance is straightforward. You should drain the reservoir regularly (daily or per manufacturer schedule) using the drain valve to remove accumulated moisture and condensation. Additionally, periodically inspect the exterior coating for damage, check all port connections for tightness, and verify that mounting brackets and bolts remain secure against vibration loosening.

Can this air reservoir handle extreme temperature and environmental conditions?

Yes. The high-strength steel construction and corrosion-resistant coating are engineered to perform reliably across a wide temperature range and in harsh environments—including exposure to road salt, mud, water spray, and temperature fluctuations typical of long-haul and off-road heavy truck operations.

What is the typical lead time for bulk orders of this air reservoir?

Lead times depend on order quantity and current stock levels. For standard quantities, we typically ship within 3–7 business days. Larger bulk orders or custom-packaged shipments may require 10–15 days. We recommend contacting our sales team directly for a precise delivery schedule based on your specific requirements.
